I've started using it now and I'm very pleased...i am very very happy with this..
As a beginner, I can't tell you right now what this device is like.
Very strong on higher levels, must start with level 1. It's sensitive around the jaw area for me but tolerable. I saw results after multiple uses. Must apply cream/moisturizer prior to use for proper conduction.
Hmm... I bought this on sale, and use with medicube jelly. I do notice a difference in the brightness of my skin when I use it, and my face looks more lifted in a subtle way. I haven't been very consistent with it, though. I should try it again!
